We're about:

Join the Natural History Society of Maryland to meet other nature lovers, outdoor enthusiasts, naturalists, and similarly inquisitive minds. We offer a wide variety of programs for the beginner to the advanced naturalist, and from informal social events to in-depth courses.

Everyone is welcome, but membership offers many free programs and discounts on others. So join us in a search for reptiles and amphibians, a canoe trip on the Chesapeake Bay, or to learn everything there is to know about Maryland dragonflies - it's up to you!

The mission of the Natural History Society of Maryland is to foster stewardship of Maryland's natural heritage by conserving its natural history collections, educating its citizenry, and inspiring its youth to pursue careers in the natural sciences.

The Natural History Society of Maryland (NHSM) is a 501(c)(3) nonprofit corporation founded in 1929. Its extensive collections of Maryland flora, fauna, fossils, and minerals, dating back to the early 1800's, are a rare and valuable asset to the State of Maryland.
